DesignerJeff ParkMililani, Hawaii

One fateful day in 2005, he walked into Ken Onion’s shop in Kaneohe, Hawaii, and never left. Well, that’s not entirely true, but he’s certainly made an impact on the world-class knife maker and has learned a thing or two along the way. Jeff Park is a detail-oriented type of guy, and by that we mean he’s an absolute perfectionist, and it shows in his simple, yet flawless designs. He’s an artist in the most fundamental respect: form follows function, and his knives reflect a remarkable understanding of both.
